Potential Payments Upon Termination or Change-in-Control

We have entered into employment arrangements that, by their terms, will require us to provide compensation and other benefits to certain of our NEOs if their employment terminates or they resign under specified circumstances. Vesting of awards granted under our Omnibus Incentive Plan is also subject to acceleration in certain circumstances, including a grantee’s termination as a result of death or disability, or a Qualifying Retirement. See “Elements of Our Executive Compensation Program—Long-Term Incentive Awards Granted in Fiscal 2025.”

The following discussion summarizes the potential payments upon a termination of employment in various circumstances. The amounts discussed apply the assumptions that employment terminated on February 1, 2026 or that a change in control occurred on February 1, 2026, taking into consideration the applicable employment agreement in effect as of February 1, 2026 and notwithstanding that Messrs. LeClair and Whittenburg each retired effective April 1, 2026. See “Narrative Disclosure to Summary Compensation Table and Grant Plan-Based Awards Table-Employment Agreements” above for a description of the NEOs’ respective employment agreements effective during fiscal 2025.

Estimated Benefits upon Termination without “Cause” or Resignation due to a “Change in Employment”

Upon termination without “cause” or resignation due to a “change in employment” or “good reason,” as applicable, each NEO is entitled to contractual severance benefits payable on termination plus payment of COBRA premium costs, as quantified in the table below.

(1)Based on salary in effect as of February 1, 2026.

(2)Payment of the COBRA benefit payment will cease in the event that an executive becomes eligible for health benefits coverage from a subsequent employer.

(3)Mr. LeClair retired from the Company and the Board effective April 1, 2026. In connection with his retirement and notwithstanding the amounts stated in the table above, Mr. LeClair did not receive any severance benefits upon termination of his employment.

In connection with his retirement and notwithstanding the amounts stated in the table above, Mr. Whittenburg and the Company entered into a Mutual Confidential Retirement and Release Agreement, pursuant to which Mr. Whittenburg received a lump sum payment equal to $206,632, in lieu of any other payments in respect of his employment agreement or otherwise.
